5)m<4=13°[being vertically opposite angle)

6)m<2+<3=180°(Being straight angle)

or,m<2=180°-110°

m<2=70°

7)m<1+m<4=180°[being straight angle]

or,m<1=180°-65°

m<1= 115°

This creates a right triangle. One leg of the triangle is 25 feet and the other is 10 feet. To find the length of the ladder, we must use Pythagorean theorem.

a = 25

b = 10

c = ?

(25)^2 + (10)^2 = c^2. Square all the terms to the left of the equation and add them together.

725 = c^2. Take the square root of each side.

c = 26.93 feet.

The ladder needs to be 26.93 feet tall.
